So, first of all: I think it’s crap and a very weak signal from Habeck.
But I can still explain it to myself: The solar installers have been telling the fairy tale of too low feed-in tariffs and maximizing self-consumption for years. That seems to be enough for the industry to boom and was already well utilized before supply shortages and war. There are even more and more people who voluntarily forego the money from the feed-in tariff...
Well, in any case, a photovoltaic system can pay for itself through self-consumption alone. Even faster with a heat pump and an electric car. And because of that, this private sector doesn’t need much support. It’s already running. (And when something is running, subsidies have to go away again, that’s how it is.)
What doesn’t work anymore with the low feed-in tariff are full feed-in systems on outbuildings, warehouses, sheds, apartment buildings, etc. THEY must be subsidized. They are usually large and help significantly with the energy transition.
The only catch is unfortunately that the surplus feed-in providers are increasingly being pushed towards small "self-consumption optimized" systems. And that is exactly the wrong thing. Both for the wallet and for the environment. Therefore, I am in favor of quickly improving this and paying at least 8-9 cents. And with that, money is still being given away, since the electricity is usually worth more!
